[Respiratory modulation of unit activity in the olfactory bulb of tracheotomized rats].
Unit activity, most probably from the mitral cells, has been recorded in the olfactory bulbs of anesthetized and tracheotomized rats. Two of 11 cells still increased their firing rate significantly during inspiration, although the airflow through the nasal cavity had been totally suppressed; the rest of the sample was not modulated according to respiratory activity.
